Over world Update(part 1)
- added an over world! this will be the main hub of the game, centered in 3 major structures
>the campfire: to help you survive in the cold and empty landscape of an ice age this fire will be the only thing between you and complete freeze
>the dungeon entrance: your main source of wood, delve there and come back to keep the fire alive
>the shrine: nothing for now (will be added in the over world part 2)

- fixed bug in which the door could spawn on top of the exit door
- 'almost' fixed bug in which a door wouldn't spawn (might still happen sometimes)

new instructions:
- while on surface press [X] while on the campfire to fuel it with collected wood.
- to enter the dungeon for the first time bring the key and interact with the door, after that simply interact with it to open.

-while in the dungeon press [H] to make the dungeon shuffle it's rooms and put you close to the surface, you still need to bring the key to the exit door and open it.

- you get a game over if the fire ever dies, keep track of it with a timer on the bottom right side of the screen, it'll tell you how much time you have left.
- in case you get a 'game over', press any key to reset the game.
